IMPROVEMENT IN STREET-CAR HEATERS.l

Specification forming part of Letters Patent No. 2l 1,2111., dated J anna-ry 7, 1879 application filed December 4, 1378.

Figure 1, represents a central transverse section of the heater when attached to a car. Fig. 2 is a longitudinal sectional view of the heater disconnected; Fig. 3, a plan view of a portion of the same; and Fig. 4, a detached view, showing the escape-passagefrom the hotair chamber.

In order to enable others to understand and apply my invention, I will rst proceed to describe its construction and operation, and to i subsequently point out in the claims its novel characteristics.

In the drawings similar letters of reference indicate corresponding parts in the several gures.

a a, Fig. 1, represent the iloor of a car, and

I) b the passenger-seats as ordinarily arranged.

The heater is suspended beneath the floor, with its register c and extension-pipes (Z d resting flush with or adjacent to the interior surface, as shown.

The ire-pot e is provided with a pivoted grate, f, hinged cover g, ash-pan h, and draftregulator fi, each being supplied with devices for adjusting and operating them from the interior of the car.

The ash-pan h is opened or closed by means of the rod k, a chain, Z, being connected at its upper extremity, as a convenient device for raising and lowering the same, and arresting its movement at any desired position, which may be effected by passing a pin transversely through one of the chain-links, as shown in Fig. 3.

The grate is pivoted centrally and dumped by means of the rod m and intermediate bellcrank lever, n, the rod m being provided with a jointed extension, o, (shown in Fig. 3, and dotted lines, Fig. 2,) to facilitate its operation from the interior of the car, and form a locking device in its horizontal position to prevent the grate from tilting.

The draft-regulator consists of .a sliding plate, i, perforated to register with corresponding perforations communicating with the ashpit, and is operated by means of the vibrating lever p.

The register c is arranged in the perforated hinged cover, and is ilush with the oor-surface. It is composed of a sliding plate correspondingly perforated, and moving in guideways r r, and adj usted by means of the button s.

A depending arm, t, Figs. l and 4, is rigidly attached to the sliding plate c, and having its lower end bifurcated to Ven gage with the stud u when the cover is closed. This lstud u is connected with a perforated slide, o, which covers an escape-passage from the heatingchamber, forming the space between the cover g of the fire-pot and the register c.

The object of the connection between the register c and the slide u is to direct and regulate the radiated heat from the heating-chamber, the arrangement of the arm t and stud u causing the slide o to open the passage when the register c is closed, and in the opening movement of the latter to close the former. A partial opening of the register and a co incident movement of the slide will regulate the heat from this source, and the temperature may thus be governed.

The hre-pot c is supplied with fuel from the elevated reservoir fw, which is arranged-beneath the passenger-seat b, as shown in the sectional view, Fig. 1. This reservoir fw is constructed in the form of a hopper, in order to increase its capacity, and also to insure gravitation of the fuel to the fire-pot. An opening, x, is provided for the introduction of the fuel, and the discharge-orifice y may be supplied with an adjustable gate to regulate the fuelfeed. The outboard side of the reservoir may be perforated, if found necessary, as shown at e, Fig. 1, to allow a ventilation of the same.

The extension radiating-pipes d d are connected with the upper portion of the iire-pot, and form a circuitous passage through a portion of the car, and their exit is directed diating-pipes, to carry off the gases.

A heater may also be arranged at each end of the car, and radiating-chambers located Within the carin place of or in connection Wi th the radiating-pipes, and such details of construction concerning the strength or 'material employed in the apparatus, or in its capacity, may be made Without departing from the spirt of my invention; the object of which is to provide a heater for'this purpose that shall include all the modern appliances for operating the same, that shall be compact in its construction and economical and convenient in use, and form no obstruction to any portion ofthe space at present utilized.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. A heater for street-cars having its firepot, radiating-chamber, and operative mechanisms located beneath the door of the car, and accessible from the interior thereof, and provided with radiating-pipes passing Within the car, and an elevated reservoir for containing the fuel, connecting with the lire-pot and ar'- ranged beneath the passenger-seat, substantially as shown.

2. The register c, provided with the depending bifurcated arm t, in combination with the slide c, having the stud u, substantially as and for the purpose specified.

3. The pivoted grate f, having the lever-arm n, in combination with the connecting-rod m and jointed extension 0, whereby the grate may be operated and locked in its horizontal position, as set forth.
